+There are two such decisions today:
- `PushDownFilter` yields to a _pure extraction projection_. A pure extraction projection is a projection whose expressions are only `__datafusion_extracted_N` aliases and pass-through columns. `ExtractLeafExpressions` creates it, and `PushDownLeafProjections` moves it towards the leaves. `PushDownFilter` does not move a filter below such a projection, so the projection stays next to the scan. A Parquet scan then merges the projection into the file projection and reads only the struct le [...]
+- `PushDownLeafProjections` yields to `OptimizeProjections`. When the extraction projection cannot move below the input of a projection, for example a `TableScan` or an `Aggregate`, `PushDownLeafProjections` leaves the projection unchanged. A split in place would give a recovery projection over an extraction projection on the same input, which `OptimizeProjections` merges back. The source absorbs the leaf expressions of the original projection just as well. See [PR #26085](https://github [...]

<p>Two rules can want the opposite order for the same pair of adjacent plan nodes. Each rule then undoes the work of the other one on every optimizer pass. The plan does not reach a fixed point, so the optimizer runs more passes than necessary, and the position of the two rules in the rule list decides the plan. The optimizer can stop early when the plan at the end of a pass is the same as the plan at the end of an earlier pass, but that does not make the result independent of the rule o [...]
